Best CC plan for a tart with mortgage renewal in January

dodgie

Hi,

I have two credit cards as follows:

Virgin, £10000 limit, £7000 balance, 0% until mid next year
Egg, £10000 limit, £0 balance (previous tart card)

I also have a Tesco Platinum CC (for clubcard points, daily spend but paid off in full every month) and a Nationwide CC for overseas stuff, paid off in full again.

My A&L mortgage 2 year fixed is due to expire in January and I was wondering if this additional £10K of 'credit' on the Egg card is going to affect me positively or negatively in any way?

I'm happy to cancel it but just don't know which is best?

Cheers

Rich
